1.3 Front Door

The Critical, Major, and Minor alarm LEDs visible through the front door indicate whether a critical,
major, or minor alarm is present anywhere on the ONS 15454 SDH. These LEDs must be visible so
technicians can quickly determine if any alarms are present. You can use the LCD to further isolate
alarms.
